- Letakkan amplifier in the desired mounting location and mark the screw holes.
- Drill pilot holes if necessary, ensuring not to damage any vehicle components.
- Selamatkan amppengalir menggunakan skru pelekap yang disediakan.
4.2 Sambungan Pendawaian
Proper wiring is critical for performance and safety. Refer to the diagram below for power, ground, remote, and speaker connections.
Figure 4.2: Rear panel of the Hertz HDP4 amplifier, detailing the power input (BATT), ground (GND), remote turn-on (REM) terminals, and speaker output terminals (L/R mono for channels A and B). Two 40A fuses are also visible.
- Power (BATT): Connect a fused power cable (minimum 8 AWG recommended) directly from the vehicle's positive battery terminal to the BATT terminal on the amplebih hidup.
- Tanah (GND): Connect a ground cable of the same gauge as the power cable from the GND terminal to a clean, unpainted metal point on the vehicle chassis.
- Alat Kawalan Jauh (REM): Connect a remote turn-on wire from your head unit's remote output to the REM terminal.
- Keluaran Pembesar suara: Connect your speakers to the appropriate L (left) and R (right) terminals for each channel (A and B). Ensure correct polarity. The amplifier supports mono bridging for increased power output to a single speaker or subwoofer.
- Sekering: The amplifier is equipped with two 40A fuses. Replace only with fuses of the same type and rating.
4.3 Input Connections and Controls
The amplifier offers both RCA (low-level) and High-Level inputs, along with various crossover and gain controls.
Figure 4.3: Input and control panel of the Hertz HDP4 amplifier. This panel includes RCA pre-inputs (A PRE-IN, B PRE-IN), high-level inputs (A HI-IN, B HI-IN), and various adjustment knobs for levels, pass mode, and crossover settings. A switch for HI-IN AUTO TURN-ON is also present.
- RCA Pre-Inputs (A PRE-IN, B PRE-IN): Connect your head unit's RCA outputs to these inputs for low-level signal.
- High-Level Inputs (A HI-IN, B HI-IN): If your head unit does not have RCA outputs, connect speaker-level signals directly to these inputs. The amplifier features an auto turn-on function for high-level inputs.
- peringkat: Adjust the input sensitivity (gain) to match the output of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- Mod Pas: Select the desired crossover mode (e.g., Full, HPF, LPF) for each channel pair.
- Crossover Frequency (XOVER): Adjust the frequency point for the selected crossover mode.
- Pengganda: Use this switch to multiply the crossover frequency setting by 1 or 10, depending on your system requirements.
5. Arahan Operasi
5.1 Kuasa Permulaan
- After all connections are made and verified, reconnect the vehicle's battery.
- Hidupkan unit kepala anda. amplifier should power on automatically (if remote wire is connected or HI-IN AUTO TURN-ON is active).
- Start with the head unit volume low and gradually increase it, listening for clear audio.
5.2 Adjusting Audio Settings
Perhalusi amplifier's settings for optimal sound quality:
- Gain Matching: Laraskan amplifier's gain controls (LEVELS) to match the output voltage of your head unit. This is crucial to prevent distortion.
- Tetapan Crossover: Set the crossover frequencies (XOVER) and pass modes (PASS MODE) according to the specifications of your speakers. For full-range speakers, a high-pass filter (HPF) is often used to protect them from low bass frequencies. For subwoofers, a low-pass filter (LPF) is used.
6. Penyelenggaraan
To ensure the longevity and optimal performance of your Hertz HDP4 amplifier, ikut garis panduan penyelenggaraan ini:
- Pembersihan: Bersihkan secara berkala ampLap bahagian luar penapis dengan kain yang lembut dan kering. Jangan gunakan bahan kimia yang keras atau pembersih yang kasar.
- Pengudaraan: Memastikan bahawa amplifier's cooling fins are free from dust and obstructions to maintain proper heat dissipation.
- Sambungan: Periksa semua sambungan pendawaian secara berkala untuk memastikan ia ketat dan berkarat. Sambungan yang longgar boleh menyebabkan prestasi atau kerosakan yang lemah.
- Sekering: If a fuse blows, replace it only with a fuse of the exact same type and rating (2 x 40A). Using an incorrect fuse can cause severe damage to the amplifier or vehicle electrical system.
